Just want to ask, payroll payments for employees appeared as only one payee in banking tab, there's no existing rule for any payroll entry. Is it in payroll settings?

You need to categorize these payroll payments to reflect the correct payees. I'll walk you through this process in QuickBooks Online (QBO), @lowellasalaysay-.

Here's how:

1. Highlight the Banking tab, then select Banking. 
2. Click the correct bank account in question.
3. Under the For review tab, look for the payroll payments. 
4. Tap any of these payroll payments so you'll see the Categorize options. 
5. Assign the correct employee under the Vendor/Customer drop-down menu.
